And the result is perfect, better than I could hope for. Here is what I did.
Installed Open Broadcaster Software v0.655b
Settings--> Advanced --> keyframe interval 4
On main page, Sources (right click) --> Add--> Game capture.
Start the game and go back to OBS immediately.
Application --> select your game. Click ok.
click Start recording.
Go back to your game.
And it worked wonderful. The best news is I recorded a 3 minute video on 1280x800 and it was only 13 MBs. That is really amazing considering other softwares made it approximately 1 GB per minute.
I tried making the "Use hotkey" but it didnt work for me. The game just didnt record. I would appretiate if someone could tell us how to make it work.
I'll give you an example video from shadowplay. 9 minutes at 22MB/s total bit rate, 60fps @ 1080p.
1.5 GB file.
